or means for the cartons, and are especiallydesigned by me for embodiment in carton making,and. sealing machines such as are illustrated and described in Letters Patent- #1,096,918, issued to 'me May 19, 1914, of which this is a; divisional application.

j The main objects of this invention are: First, to provide in a carton sealing machine, an improved delivery mechanism for therahtons adapted to effectively deliver thejc artons irorn the sealing eonveyer With- 'oiiti'injury thereto. Second, to provide in a ,certon seelingfmachine, an improved delivery mechanism having these advantages,

which is simple in structure and very do ra-hle and reliable in use.

Further-objects, nnd0bjects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invent-ion is clearly defined pointed out in the'cleirns.

A structure which is a preferred embodiment of my invention is clearly in the accompanying drawing forming e part of this specification, in which:

Figure I is a detail plan View of the portion of a. csrton sealing machine m bodying the features of my inventi II is a detail vertical central ion section through the delivery mechr. the structure shown in Fig. I. Fi- & detail longitudinal section on ii spending to line S 3 of Fig. II. is a detail horizontal section. on thcorresponding to line l-4 of Fig. I.

Patented ling. 2:2, 1%16.

Divided and this application filed April 18,

the line corresponding to broken line 5-5 Fig, IV. In the drawings similar reference characters rei'er to similar parts throughout the 5- se eral views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines:

Referring to the drawing, the main frame 1 is of suitable design and structure to properly support the operative parts. Disposed centrally and longitudinally of the frame is a conveyer comprising a chain 2 provided with flights 3 and forms l. The flights 3 are adapted to receive filled car'- tons and the forms 4 are adapted to receive carton blanks from it suitable blank feeding mechanism. The rear end of the conveyor is supported by thesprocket 5 on the shaft 6. The fiights and forms move between-the eonveyer ways 7 provided for the top and bottom reaches of the conveyor chain.

The structure illustrated relates to thecarton delivery mechanism of a combined carton making and sealing machine such as is illustrated and described in my patent referred to. Further details of the oonvoyer are described herein as they form no part. tl p: -.t invention. The means for feeding the ialsnlis to the forms 4 and the filled cartons the flights are not illnstrsted as such means form no part of this The carton forming and flap l herein as they form no esent invention. My pat illustrates and describes in forming and flap ling enisni. Other t n that of said readily mechanisms are not depass. The belts t) are carried by pulleys 10 and 11, the pulleys 11 beingmounted on the vertical shafts 12 carried by the swinging frames 13. The pulleys 10 are carried by the shafts 11 mounted in suitable bearings on the main frame: The swinging frames 13 are mounted upon these shafts 14. The shafts 14 are provided with beveled gears 15 meshing with thebeveled gears 16 on the shaft (3 of the conveyer. The pulleys 10 are fixed to the shafts 14 to drive the belts. The frames 13 are s\\-'ung to and from engaging position by the cams 17 acting onthe rollers 18 on the arms 19, the arms 19 being fixed to the i'nain frame. The cams 17 are mounted on \rrtical shafts 2O carricdby the swinging frame 13. These shafts 20 are connected by the gears 21 and 2:2 to the shafts 11 so as to be driyen thereby and properly timed with the conveyer. By this a rrangrment the frames are swung from their engaging positions to permit the cartons on the formsl to pass into their engaging positions to engage the cartons on the flights 3 and deliver the same to the delivery eonvcyer 18.

To insure positive gripping of thepackages by the belts I provide belt supports comprising supporting bars 23 arranged between the pulleys and carried by the cross bars 24- mountcd on the bars 25. The bars 25 are mountcd'on blocks 26 carried by the shafts 12-, see Fig. V. The pulleys [.1 are loosely mountcd on this shaft 12 and the shafts are pivoted in the frames l3 to permit the swinging of the belt supports. The belt supports arc actuated by cams 27 on gcars 2i which engage rollers 28 on the belt supporting bars 25, so that as the gears are revolved the belts are swung toward carh other to engage the cartons carried by the convcycr flights 3, the belts being swung apart to permit the cartons carried by the frame to pass.

1y this simple arrangementof the parts I IH'UVltlt a delivery mechanism which offectivcfvdclivcrs the cartons without injury thereto and allows. as stated. a part of the cartons to pass. The delivery mechanism, however, is well adapted for use on ma rhinos where it is desired to deliver all of tho cartons. l have illustrated and drsrribed my im u'o\ 'cnu-.nts as embodied in thc marhinc adapted for making and scallug tlucartons and have not altcmpte-l to illustrate or drsrribo the same as embodied in ollu-r machines. as l believe the disclosure made will enable those skilled in the art to which my invention rclatis to adapt. or (-mlmdv tln' sumo as may be drsircd.

lla\ing thus described my invention, but l rlaim as new and desire to sccnre by lltlttl'h' latrnt. is:

l. in a structure of the class described, the combination with the conveyor, a di5- charge means comprising belts arranged in opposed pan-s at the s des of the conveyer,

vertical shafts arranged one at each side of the conveyer,swinging frames mounted on said vertlcal shafts, pulley shafts on said swingin frames, pulleys for said belts mounted on said vertical shafts and said shafts carried by said swinging frames, cam

shafts carried by said swinging frames,

the combination with the conveyer, a discharge means comprlslng belts arranged in opposed pairs at the sides of the conveyer, verticalshafts arranged one at each side of the conveyer, swinging frames mounted on said vertical shafts, pulley shafts on said,

swinging frames, pulleys for said belts mounted on said vertical shafts and said shafts carried by said swinging frames, cam shafts carried by. said swingingframes, gears connecting said cam shafts to said vertical shafts, cams on said cam shafts, and members coacting with said cams to swing said frames as the cams are revolved, all roarting for the purpose specified.

'3. lay a structure of the class described, the combination with the conveyer, a discharge means comprising opposed belts, driven shafts, swinging frames mounted on said driven shafts, pulley shafts on said swinging framcs, pulleys for 'said belts mounted on said .driven shafts and said shafts carried by said swingingframes, rams for said mvingingfranics gcarcd to said drivrn shafts, bolt supports comprising bclt' engaging members and supports therefor mounted at their outer ends on said pulley shafts carried by said swinging frames, and cams arranged to act on said belt supports, all roacting for thepurpose specified.

(lisrhargv means comprising opposed belts, driven shafts. swinging frames mounted on said driven shafts. pulley shafts on said swinging frames, pulleys for said belts mounted on said driven shafts and said shafts carried by said swinging frames, and rams for said swinging franu-s geared to said driven shafts. all roasting for the purpose specified.

5. in a Stl'tH'lltl'P. of the class dcscf'ibcd, the rombination with the conveyor. discharging means comprising opposed bolts,

swinging supporting frames therefor whereby the belts are swung to and from engaging position, means for actuating said frames, opposed supports over which said belts travel, and means for swin ing said supports toward each other to iring the belts into engaging position.

6. In a structure of the class described, the combination with the conveyer, discharging means comprising opposed belts, swinging supporting frames therefor whereby the belts are swung to and from engaging position, and means for actuating said frames.

7. In a structure of the class described, the combination with the convever, (lischarging means comprising opposed belts, opposed supports over which said belts travel, and 'fneans for swinging said supports toward each other to bring the belts into engaging position.

8. In a structure of the class described, the combination with the conveyer. a dis charge means comprising opposed belts, swinging supporting frames therefor, where by the belts are swung to and from engaging position, and means for actuating said frames.

In witness whereof, I have hereunto set my hand and seal in the presence. of two witnesses.
